Merger Agreement

On Feb. 5, 2007, NetRatings announced that it had signed a definitive merger agreement pursuant to which The Nielsen Company and its subsidiaries will acquire the outstanding publicly held minority interest in NetRatings for $21.00 in cash per share. Nielsen beneficially owns approximately 60 percent of the company's currently outstanding shares. NetRatings' board of directors unanimously adopted and approved the merger agreement following the unanimous recommendation of a special committee of NetRatings' board of directors comprised solely of independent directors. The merger is expected to be completed in the second quarter of 2007, subject to customary conditions and approvals. The exact timing is dependent on the review and clearance of necessary filings with the Securities and Exchange Commission.
